Thank you for purchasing a PT-510/PT-510W series submersible pressure transmitter from APG. We
appreciate your business! Please take a few minutes to familiarize yourself with your PT-510 and this
manual.
PT-510/PT-510W series submersible pressure transmitters oer reliability in harsh industrial conditions. The
small size, and all welded, all stainless steel body make the durable PT-510/PT-510W the perfect instrument
for static and dynamic pressure measurement. The PT-510 comes with a Delrin nose cone, suitable for clean
water use, while the PT-510W has a stainless steel cage for additional transducer protection in wastewater
environments.
Reading your label
Every APG instrument comes with a label that includes the instrument’s model number, part number, serial
number, and a wiring pinout table. Please ensure that the part number and pinout table on your label
match your order.

Chapter 2: Installation and Removal Procedures and Notes
• Tools Needed
• Tools necessary to make electrical connection.
• Mounting Instructions
Your PT-510/PT-510W series submersible pressure transducer is designed to be free-hanging.
• Electrical Installation
• Connect the wires of your PT-510 to your control system according to the pinout table above.
NOTE: If your PT-510 has a vent tube, do not seal, cover, or close the vent tube with
anything other than an APG-provided venting cap or desiccant drying cartridge (See Figure 3.1 and 3.2). Unapproved seals or covers will prevent proper sensor operation.
Removing your PT-510/PT-510W from service must be done with care. It’s easy to damage your sensor if you
are not careful to follow these guidelines:
• Retrieve the sensor from the vessel. Follow any and all procedures for safely isolating any media contained inside the line or vessel.
• Carefully clean the sensor’s tting and diaphragm of any debris (see General Care) and inspect for
damage.
• Store your sensor in a dry place, at a temperature between -40° F and 180° F.
Chapter 3: Maintenance
• General Care
Your PT-510/PT-510W series pressure transmitter is very low maintenance and will need little care as long as
it is installed correctly. However, in general, you should:
• Avoid applications for which the transmitter was not designed, such as extreme temperatures, contact
with incompatible corrosive chemicals, or other damaging environments.
• Avoid touching the diaphragm. Contact with the diaphragm, especially with a tool, could permanently
shift the output and ruin accuracy.
• Clean the diaphragm or the diaphragm bore only with extreme care. If using a tool is required, make
sure it does not touch the diaphragm.
IMPORTANT: Any contact with the diaphragm can permanently damage the sensor.
Condensation in the vent tube can damage the electronics in your sensor, resulting in unreliable readings.
APG oers two methods of preventing vent tube condensation: a venting cap, and a desiccant drying
cartridge.
The venting cap is a PVC tube with a hydrophobic patch that allows moisture to pass out of the tube without
allowing water in (See Figure 3.1). The cap is sealed by an o-ring, and is easily installed in the eld.
The desiccant drying cartridge with vent tube adapter absorbs any moisture in the vent tube to keep vapor
from condensing (See Figure 3.2). The installation of the desiccant drying cartridge is quick and easy.
Common installation methods are cable tie, Velcro, and cable clamps.

NOTE: Desiccant crystals change from blue to pink as they become saturated. Car-
tridge must be replaced when all crystals have saturated.
IMPORTANT: Do NOT use desiccant cartridge in the presence of vapors or liquids con-
taining phosphate esters, synthetic lubricants, hydrocarbon solvents, methanol, acetone,
lacquer solvents, or other organics.
Should your PT-510 series pressure transmitter require service, please contact the factory via phone, email,
or online chat. We will issue you a Return Material Authorization (RMA) number with instructions.
